CARBURETOR.

SPCIFICATION forming part ofv Letters Patent No. 350,382, dated October 5, 1886.

Application tiled November 25, 1885. Serial No. 183,025.

T 0 all whom it may concern.-

Beit known that I, JAMEs D. MERRITT, a citizen of the United States, 'residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Carburetors; and I do hereby declare the following to be a full, clear, and

and combination of elements hereinafter fully described, and then specilicall y designated by the claim.

In order that those skilled in the art to which my invention appertains may more fully understand the operation of my invention, I will proceed to describe the same in detail, referring byletter to the accompanying drawings, forming a part of this specification, in which- Figure lis a side elevation of my improved apparatus; Fig. 2, a detail side elevation showing the drum-casing and feed-box connected by pipes, the said casing being broken away; Fig. 3, a detail section of the drum-casing'and feed-tank, the drum itself being shown in side elevation; Fig. 4, a front elevation of a pair of drums, the casing being sectioned; and Fig. 5, a similar view showing a series of drums.`

Similar-letters denotelike parts in the sevi eral figures of the drawings.

A is the carbureting-drum, which is mounted .on an axis, B. The sides of the drum are reticulated, as shown in Fig. 3, and the interior is loosely packed with any suitable absorbent material, preferably sponge.

C is the casing within which the drum is mounted, and D is the gasoline-feed box im# mediately adjoining said casing.

E are perforations extending through the casing from the box D, by means of which the gasoline may nd its way within the drum- (No molel.)

casing,and thence th roughthe reticulated sides into the drum itself. is'forced into the drum by means of any suitable rotary pnmp, F. This pump has an outlet-pipe, G, through which the air is introduced within the drum. (See Figs. 1, 4, and 5.)

H is the outlet-pipe through which the carbureted air passes. l

I isthe main gasoline-tank, having an outlet, J, at the bottom thereof extending within the supply-box D. The bottom of this outlet is closed by a floatvalve, K, so that when the gasoline is at a certain level in said box the supply will cease. The gasoline iiows through the perforations E into the drum-casing, and thence into the drum, so thata liquid-level is established within said box and drum. By the supplying of the gasoline from an outside tank through a pipe, and by the automatic regulation of said supply by means of thefloatvalve, there is a constant iiow of gasoline during the operation of the apparatus, while at the same time the gasoline is of a high temperature, comparatively, because in passing from the supply-tank into the box it is exposed to the temperature of the air through the medium of the outlet J.

L is an aircirculating pipe extending from the top of the main tank to the top of the feedbox, and the object of this pipe is to afford a vent for the tank, to permit the free flowing ofthe gasoline,while at the same time a complete circulation of airis effected between the air-pump and the main tank, thereby still further raising the temperatureof the gasoline.

rlhe chief obstacle met with inan apparatus of this description is that vthe volatilization of the hydrocarbon is effected by intense cold produced by the evaporation of the liquid. My improvement, as hitherto described, has in View to overcome this difficulty; but in order to still further perfect my apparatus, es

pecially when it becomes desirable to employ more than one carbureting-drum, I have constructed the casings of cach drum separate, so that they will be exposed to the air nearly throughout their supereial area, (see Figs. 4 and 5,) and have established an external communication between the casings by means of roo pipes M N above and below the axis B. By this construction it will be readily understood The air to be carbureted that refrigeration is impossible, since the gasoline and carbureted air are constantly affected by the temperature of the outside atmosphere.

I do not wish to be confined to a feed-box immediately adjoining the drum'casing, since the feed-box may be remote from the casing and connected therewith by suitable pipes, as shown in Fig. 2. The lnain tank is preferably set in the ground, in order to still lfurther preserve an even temperature.

I do not wish to be understood as claiming the feature of feeding the gasoline from the bottom of a supply-tank and regulating said feeding by means ol" a oatvalve, since I am aware that these features are fully disclosed in the state of the art relating to carburetors; and, further, I do not desire to lay claim, broadly, to the rotary pump and druin in cornbination with the extended gasoline-holding base, since I ain aware that such an arrangeinent of parts has heretofore been used, and is exhibited in several United States patents.

Having thus described my invention, what Iv claim as new, and desire to secure by Letters Patent, is

In a carbureting apparatus, the vcombination7 with the drum having reticulated sides and loosely packed with absorbent material, of a feed-box adjoining or connected with the drum-casing and separated therefrom by a perforated partition, a supply-tank located in a higher plane than that of the said box, and having outlet-pipe extending from the bottom thereof into the box, Iioat-valve at the mouth of said pipe, and an air-vent pipe leading from the tank to the box above the liquid level, substantially as shown and described.

In testimony whereof I affix my signaturein presence of two witnesses.

JAMES D. M ERRITI.
